Add sp_regnum_from_eax/pc_regnum_from_eax to i386 gdbarch_tdep
* amd64-tdep.c (amd64_x32_init_abi): Set sp_regnum_from_eax to AMD64_RSP_REGNUM and pc_regnum_from_eax to AMD64_RIP_REGNUM. * i386-tdep.c (i386_gdbarch_init): Initialize sp_regnum_from_eax and pc_regnum_from_eax to -1. Update SP regnum from sp_regnum_from_eax and PC regnum from pc_regnum_from_eax if needed. * i386-tdep.h (gdbarch_tdep): Add sp_regnum_from_eax and pc_regnum_from_eax.
